What Applied Thermal Control does
Applied Thermal Control Ltd (ATC) is a UK-incorporated, privately held designer and manufacturer of precision thermal control equipment headquartered in Barrow upon Soar and operating as part of SDI Group. Its portfolio is organized into active recirculating chillers (0–500W through 14.5kW, including industrial and 19-inch rack-mounted variants) and passive cooling solutions comprising A-Series airblast coolers (1–40kW), water-to-water heat exchangers across the XR, XF and large XF050–XF085 series (up to 200kW), and F-Series flatbed coolers. The technical core is recirculating chillers with a stated 0.1°C temperature stability, supported by proprietary heat-transfer fluids (Hexid and CoolFlow) and a broad accessories range covering sensors, communications, pumps, filtration and environmental protections, with CE/UKCA compliance and IP24/IP54 protection ratings.
ATC serves two primary customer segments: end users such as manufacturing facilities and laboratories requiring precise process temperature control, and OEMs integrating cooling into equipment such as laser systems, hydrogen electrolysis stacks, resistance welding machines, X-ray sources, electronics and medical devices. Revenue is generated primarily through hardware sales of chillers, coolers, heat exchangers and consumable fluids, supplemented by installation and commissioning services and recurring service and maintenance contracts. The go-to-market combines direct field sales in the UK with a global distributor and service-agent network covering EMEA and beyond, alongside OEM co-development partnerships.
ATC operates an 11–50 employee UK design and manufacturing operation with stable domestic supply chains, holds ISO 9001:2015 and ISO 14001:2015 certifications, and is in the midst of a low-GWP refrigerant transition to preserve regulatory eligibility. Recent management additions — General Manager Ashley Rolfe (February 2026) and Head of Sales Neil Forknall (March 2026) — point to an active scaling agenda, building on the 2019 Thermal Exchange merger that broadened the airblast cooler range and international service coverage.
